2x8S Bicycle Trigger Shifter

What should you do if the chain gets stuck or teeth jump during the Bicycle Trigger Shifter shifting process?

When the Bicycle Trigger Shifter encounters chain jamming or tooth skipping during shifting, the rider should first remain calm and then follow the steps below to deal with it:
Stop riding: When you find that the chain is stuck or skipped, you should stop riding immediately to prevent further damage to the chain or gears.
Check chain position: Look closely at where the chain is stuck to determine where the problem lies. The chain may be stuck on the gears, derailleur or derailleur rollers.
Try manual adjustment: Carefully move the chain, trying to find where it's stuck. Sometimes a stuck chain can be freed by gently shaking the chain or rotating the pedal backwards.
Clean the chain: If the chain is stuck due to debris or dirt, carefully remove it using your fingers or a tool. After cleaning, you can apply an appropriate amount of lubricant to the chain to ensure that the surface of the chain is smooth to reduce friction and the possibility of getting stuck again.
Check and adjust the derailleur: If the chain still skips teeth, the derailleur may not be adjusted properly. At this time, it can be adjusted according to the type of transmission by adjusting the limit screw, tightening the cable or using a speed regulator. Make sure the chain switches smoothly between gears when shifting.
Replace worn parts: If the chain, chainring, or cassette is worn excessively, it can also cause skipping. Check these parts regularly for wear and replace as necessary to ensure proper operation of the chain and chainrings.
Check and replace the transmission cable: If none of the above steps solve the problem, you can check to see if the transmission cable is bent or broken. If there is, a new transmission line should be replaced in time.
After completing the above steps, try shifting again to see if the chain can run smoothly. If the problem persists, it is recommended to seek help from a professional bicycle repairman to ensure the proper operation of the bicycle's shifting system.
In addition, in order to prevent the chain from getting stuck or skipping teeth, it is recommended that riders clean and lubricate the chain regularly to keep the bicycle in good condition. At the same time, pay attention to smooth speed changes during riding to avoid sudden acceleration or deceleration from causing impact on the speed change system.
